Example of overload formation in dynamic mode of operation during lifting the weight
8.13 Dynamic lift (DL) function
Crane function -
DYNAM. LIFT (DL)
(ID 1068) is used to adjust the maximum lift speed according
to the actual weight. Maximum speed is reduced for higher weight.
For correct operation of the dynamic lift is necessary to set the parameters, which determine the
calculation of the quantity "Load" (ID 854) as set by "Overload switch".

Description
Load. signal
843
Selection of the parameter, which will be used as calculation source for
the displayed value „Overload“.
100% Load
844
It is used to conversion to relative units. Value of the selected load
signal (ID 843) that equals 100% of the load.
Load filter
851
First order filter, which is used for noise or short peaks of the selected
load signal (ID 843) reduction.
